Hi! My name is ***** ***** I will be assisting you. Let's get started!
The "key" that you are referring to is probably the product/license key. As far as I can tell, the business is still around.
Here is their website: https://www.brownbearsw.com/
Along with their phone number: 1-***-***-****
If they can help you with the product key, you should be able to use the program again.
